haemolytic toxicity of Pulsatilla saponin A (PSA) has hampered its clinical development as an injectable anticancer agent. To circumvent this challenge, twenty PSA derivatives with C ring or C-28 or C-3 modifications were synthesized and evaluated for cytotoxicity against seven selected human tumor lines, as well as for haemolytic toxicity. Structure-activity relationship (SAR) and structure-toxicity relationship
